Application filed January 19, 1903. Serial No. 139,501- (No model.)

To all whom it may concern:

Be it known that I, ORREN A. SAWYER, a citizen of the United States,residing at Lowell, in the county of Middlesex and Commonwealth ofMassachusetts, have invented an Improvement in AutomaticFilling-Replenishing Looms, of which the following description, inconnection with the accompanying drawings, is a specification, likecharacters on the drawings representing like parts.

This invention relates more particularly to looms provided with meansfor automatically replenishing the filling at the proper time as, forinstance, when the filling in the running shuttle fails or becomesexhausted to a predetermined extent. An automatic fillingreplenishingloom of this general type forms the subject-matter of United StatesPatent No. 529,940, a fresh supply of filling being insertedautomatically in the running shuttle upon the occurrence of certainchanges in the filling therein. In such looms it sometimes happens thatwhen the loom is at rest and is turned over by hand the movement of thelay will effect a transfer of filling to the shuttle, and the weavermust either efiect the threading of the latter by hand manipulationbefore starting the loom or upon start ing up another filling-supplywill be transferred to the shuttle, because of failure of the first oneto properly thread. Thus there is an unnecessary operation of thereplenishing mechanism and depletion of the filling feeder or hopper,and, furthermore, the shuttle may not be in the ireplenishingshuttle-box, or it may be improperly positioned therein forreplenishment when the replenishing mechanism is operated.

The present invention has for its object the production of very simpleand efficient means for preventing the operation of thefilling-replenishing mechanism when the loom is at rest-i. 6., when theshipper is in stopping position and the power is off the loom. 5 Thevarious novel features of the invention will be hereinafter described inthe subjoined specification and particularly pointed out in thefollowing claims.

Figure 1 is a front elevation, centrally broken out, of a portion of alo om provided with automatic filling-replenishing mechanism with oneembodiment of the invention applied thereto; and Fig. 2 is a right-handside elevation thereof, the filling-feeder of the replenishing mechanismand the lay and replenishing shuttle box being shown in transversesection.

The loom-frame A, the lay A provided with a hunter C the breast-beam Asupporting a stand A which carries the filling 6o feeder or hopper,comprising, essentially, two parallel and rotatable disks,only one ofwhich, as A, is shown in Fig. 2, the transferrerf, fulcrumed on thehorizontal fixed studfand having a ti p-engaging device 22 for thefilling-carriers b, the armf depending from the transferrer, the notchedholding-plate N, Fig.

1, for the shipper S, the latter being the only member of the stoppingmeans herein shown, and the controlling or operating rock-shaft d areand may be all substantially as in United States Patent No. 664,790,dated December 25, 1900. As in said patent, a headed rocker-stud m ismounted on the end f of the transferrer, and by a spring s (see Fig. 1)the stud is turned at times in the direction of the arrow 12, Fig. 2, anarm on, secured to the stud, having a lateral lug m, against which bearsthe branch 11 of the shuttle-feeler y The rock-shaft d has fast upon ita rocker-arm d held by a spring (1 in the position shown in Figs. 1 and2 when the loom isrunning properly, and at such time a notched dog m,which is adjustably secured to the arm m is held out-of the path of thehunter 0 When filling replenishment is tobe effected, the rock-shaft dis turned in the direction of the arrow 65, Fig. 2, lifting the arm (V,and at such time the spring e is free to swing the shuttle-feelerrearwardly across the raceway as the lay beats up, and at the same timethe arm m and dog m swing upward on the stud m as a fulcrum, bringingthe dog into position to be engaged by the hunter O 5 The continuedforward movement of the lay after such engagement operates to rock thetransferrer on its fulcrum fand transfer a filling-carrier from thefeeder or hopper to the shuttle, all in well-known manner. we

In order to prevent the operation of the re plenishing mechanism whenthe loom is at rest, such operation being effected by turning the loomover by hand, means are provided to prevent the turning of the dog minto the path of the hunter C when the shipper is in stopping position.

In Fig. 1 the stopping, position of the shipper is shown in dottedlines, and the full lines indicate the running position of the shipper.A slide rod or bar h is mounted in the loom-frame below the breast-beam,as shown in Figs. 1 and 2, and extended from the replenishing side ofthe loom to the opposite or shipper side, said slide-rod at the shipperside having two rearwardly-extended pins h and 7L secured to it andextending at opposite sides of the shipper, as clearly shown in Fig. 1.At its opposite end the slide-rod is upturned and turned rearwardly topresent a detent h provided with a beveled rear face 35. The beveledface is substantially parallel to the under side of the arm at when thelatter is in normal position, as will be seen by reference to Fig. 2,and when the shipper is in running position the detent is at one side ofsaid arm. The slide rod or bar It is so located that when it is movedlongitudinally to the left the detent h will be brought beneath the arm'm near its upper or forward end. When the detent is in such position,it will be manifest that the spring 5 cannot operate to turn the stud mthe arm, and its attached dog m, even when the controlling rock-shaft dis turned in the direction of the arrow 65. Consequently when the detentis in its operative position the dog cannot be moved into the path ofthe hunter 0 and the replenishing mechanism cannot be actuated. Themovement of the detent into operative position is effected by or throughthe shipper when the latter is released from its holdingnotch in theplate N, for at such time the shipper will engage the pin h and willmove the slide-rod h to the left far enough to bring the detentimmediately underneath the arm on, as described. When, however, theshipper is moved into running position, as shown in full lines, Fig. 1,itsinner edge will engage the pin h and will slide the rod 72. to theright, moving the detent into the position shown in Fig. 1. The distancebetween the pins 77. and h permits somelost motion between the sliderodand the shipper, as the 'movement of the latter in one direction or theother is greater than is necessary to move the detent into or out ofoperative position. I To prevent movement of the slide-rod to the left,viewing Fig. 1, when the shipper is in stopping position, so that thedetent would be moved to the left past the arm m, a collar h is securedto the slide-rod, as shown in Fig. 1, to bear against the adjacent partof the loom, in which said rod is slidably mounted.

It will be manifest that so long as the shipper is in its runningposition the detent cannot be accidentally or otherwise moved into longas the shipper remains in such position.

The invention is not restricted to the precise construction andarrangement shown and described herein, as the same may be modified orrearranged in various details by those skilled in the art withoutdeparting from the spirit and scope of the invention, one practicalembodiment of which is herein contained.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- 1. In a loom, a device to govern theoperation thereof, filling-replenishing mechanism, and means to preventthe operation of the replenishing mechanism, actuated by movement ofsaid device into position to effect stoppage of the loom.

2. In a 100m, a device to govern the operation thereof,filling-replenishing mechanism, and detaining means therefor renderedoperative by movement of said device to stop the loom and renderedinoperative by movement of said device to start the loom.

3. In a loom, a shipper, automatic fillingreplenishing mechanism, andmeans to prevent the operation thereof when the shipper is in stoppingposition.

4. In a loom, a shipper, automatic fillingreplenishing mechanism, andmeans controlled directly by or through the shipper to prevent theoperation of said mechanism when the shipper is in stopping position andto permit the operation of the said mechan ism when the shipper is inrunning position.

5. In a loom, a shipper, automatic fillingreplenishing mechanism, meansto prevent its operation, and an operating connection between said meansand the shipper, to render said means operative or inoperative when theshipper is moved to stopping or running position, respectively.

6. In a loom provided with automatic filling-replenishing mechanism,means to efifect the operation thereof, including a normally inoperativedog, a shipper, and a detent for and to prevent operative movement ofthe dog, rendered operative by or through movement of the shipper intostopping position.

7. In a loom provided with automatic filling-replenishing mechanism,means, including a slidably-movable detent, to prevent the operation ofsaid mechanism, and a shipper operatively connected with and topositively move the detent into operative position when the shipper ismoved to stopping position.

8. In a loom, a shipper, automatic fillingreplenishing mechanism, meansto prevent the operation thereof when the shipper is in stoppingposition, and a connection between said means and the shipper to renderthe former inoperative by or through movement of the latter to runningposition.

9. In a loom, a lay provided with a hunter, filling-replenishingmechanism, means to effect its actuation, including a normallyinoperative dog, movable into the path of the hunter, a shipper for theloom, and. a detent rendered operative by or through movement of theshipper into stopping position, to prevent movement of the dog into thepath of IO the hunter.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
